SHOCK-AB$ORBING 'eNUBBING DEVICE FUR VEHICLEEi Application filed. December The object of my invention is to provide an efiicient shock absorber and snubber of simple and inexpensive construction, and particularly adapted for spring mounted motor vehicles.

I attain my object in a combination comprising complementary leaf springs secured at one end to the axle of the vehicle, and a member arranged longitudinally with, and centrally between the. other end of said leafsprings, and means for securing said member to the body of the vehicle, a piece movable longitudinally on said member, an operative connection between said piece and the adj acent end of the leaf-springs, and a spring element normally, but yield-ingly positioning said piece. 7

The details of construction and mode of operation of my device. are hereinafter fully described with reference to theaccompany ing drawings, in which:

Fig. 1 is a fragmentary elevation of a vehicle with my combined shock absorber and snubber connecting the body and the axle thereof across one end of a load carrying spring;

Fig. 2 is a longitudinal section through my combined shock absorber and snubber showing the details thereof, said section being taken on the line 2-2 in Fig. 1; and

Fig. 3 is a transverse section taken on the line 3 3 in Fig. 1 showing the fastening means of my invention to the body of the vehicle.

Hy combined shock absorber and snubber is adapted to be mounted on the axle (t and fixed to the body 6 of any spring vehicle. in the drawings I .show that the upper end of my device is connected to one. fender racket b of the body. My improved device comprises a pendent guide rod (Z carried by the upper mounting e and threaded in the latter and thus the relative length can be adjusted by varying the length of the engagement of the threaded portion of the rod providing a means of adjustment to any type of spring vehicle.

A sleeve 7 is mounted upon said guide rod (Z and is held between the coil springs g and 9. One end of the spring 9 bears against the nut 7i threaded on the rod 6 and the opposite end thereof bears against the sleeve f. The spring 9 is mounted between said sleeve 7 and the enlarged end or head d of said guide rod 6.

7, 1925. Serial No. 73,800.

Said sleeve carries links 2' and 2" at opposite sides and said links are fastened to eyes 2' and 9' formed in the free ends of the laminated spring elements and j. The opposite ends of springs j and 7" are fastened 1n the mounting halves 7e and K? which constitute the lower mounting element and are held together by studs Z and m. The halves 7s and 7c clip the axle a as shown in Fig. l and are connected together by bolts n and n. Sail bolts pass above and below said axle and thus the eyes j and j*", formed in the free ends of the spring elements of 7' and 7" respectively, may be adjusted by varying the relative lengths of the bolts n and it thus providing means for varying the resiliency of said springs. The tension of the springs g and 9 may be adjusted by the nut h. k

The upper mountingis adapted to the particular vehicle to be equipped with my improved device. In the accompanying drawings said mounting is shown as being fastened to the fender bracket Z) and said body. Said fender bracket is .substantially U shaped in section and the upper mounting comprises a U-shaped clip 6 in which 5 block e in Fig. 2 is fastened by means of a .tJ-bolt c". Said il-bolt passes about the pendent guide rod 0! and thus any major ad justments of the latter may be made by loosening the iJ-bolt and permitting the guide rod (Z to be moved longitudinally thereof.

In operation on a vehicle equipped with my shock absorber and snubbeif a light shock, as for instance crossing a car track, will slightly compress the spring: g and the reflex action will be retarded by the com pression of the spring 9. l t heir subjected to. a heavy shock, the spring will be compressed. and the force will be transmitted to the leaf springs 7' and 7" through the links 2' and i, which will tend to force them apart, providing additional means of absorbing the shock. The reflex action is also in this case retarded by the spring 9, which will be compressed more or less in proportion to the severity of the shock, and tend to. absorb all reflex actions.

With my arrangement of springs, whereby their actions are rendered reciprocating, the body 6 is resting on a cushioned support in which an equilibrium will always be maintained between the upward and downward thrusts; thus providing very smooth and easy riding properties.

I claim:

1. A shock absorber comprising a lateral.

ly yielding spring-element arranged in U- i'orm, a member arranged longitudinally with and centrally between the extremities of said spring-element, means for securing said spring-element and said member to the axle and the body of the vehicle respectively, a piece movable longitudinally on said mem ber, links connecting said piece with the adjacent ends of the said spring element, and an auxiliary spring element normally, but yieldingly positioning said piece on said member.

A shock absorber comprising a laterally yielding spring-element arranged in U- liorm, a member arranged longitudinally With and centrally betweenthe extremities of said spring-element, means for securing said spring element and said memb r to the axle and the body of the vehicle respectively, a piece movable longitudinally on said member, links connecting aid piece with the adjacent ends of the said spring element, an auxiliary spring-element normally, but yieldingly positioning said piece on said member, and means for adjusting the ten sion of the auxiliary spring element.

3. A shock absorber comprising, a pair of spaced complementary leaf-springs, a member arranged longitudinally with, and centrally between the free extremities of said leaf-springs; means for securing said leafsprings and said member to the axle and the body of the vehicle respectively, a piece movable longitudinally on said member, links connecting said piece with the adjacent ends of the said leaf springs, a spring ele ment normally, but yieldingly, positioning said piece on said member.

4. A shock absorber comprising, a pair of spaced complementary leaf-springs, a member arranged longitudinally with, and centrally between the free extremities of said leaf-springs; means for securing said leafsprings and said member to the axle and the body of the vehicle respectively, a piece movable longitudinally on said member, links connecting said piece with the adjacent ends: oi the said leaf-springs, a spring located and bearing on each side of said piece, and nor-- mally, but yieldingly, positioning the latter.

5. A shock absorber comprising a pair of spaced complementary leaf-springs, a mem-- ber arranged longitudinally with, and centrally between the tree extremities of said leaf-springs; means for securing said leai springs and said member to the axle and thebody of the vehicle respectively, a piece movable longitudinally on said member,

links connecting said piece with the adjacent ends of the said leaf-springs, and a coil spring located and bearing on each side of said piece, and normally, but yieldingly, positioning the latter.

6. A shock absorber comprising a pair of spaced complementary leaf-springs, a mean ber arranged longitudinally with, and centrally between the free extremities oi said leaf-springs; means for securing said leafsprings and said member to the axle and the body of the vehicle respectively, a piece mov able longitudinally on said member, links connecting said piece with the adjacent ends of the said leaf-e )rings, a spring-element normally, but yieldingly, positioning said piece on said member, and means for adjusting the tension oi? the latter spring.
